All sage green

Shopping around for a handprinted kitchen at the moment. Really love the idea of sage green kitchen units but a lot of the inspiration pictures seem to have them mixed with other colour units, and I'm wondering if there's a reason why...

Do you think all green units would be tiresome after a while? I could mix and match them but will have to alter my overall colour scheme in that instance.If it helps, mostly bottom units and pantry doors (I may have one wall unit).
